don't believe their marketing hype. An intercooler (think of it as simply a heatsink) is not a performance upgrade in itself, it plays more of a supporting role when you have upgraded the turbo, exhaust and upped the boost via a tune. If you are stock standard you will not see any performance gain.Hi, i have a 2010 FXT and am thinking of upgrading to the Hyperflow top mount intercooler. According to their website it can give up to 15kW increse without any other mods. How true is this and is it worth it?
